In this paper, a contour error control strategy based on spatial iterative learning (sILC) is developed for repetitive processing of five-axis computer numerical (CNC) machine tools. A curve approximation method with an adaptive moving window to achieve accurate tool position and orientation estimation, sILC proposed. The compensation derived using algorithm modify the geometric reference path ...

A long flexible material called the web is converted into final product through various processes such as printing, drying, coating, and laminating using a handling system. The transported from an unwind roller to rewind some guide drive rollers in servo motors control regulate their rotation velocity or torque system, where tension transportation controls play important role achieving high qua...

In this work, we apply the iterative learning control approach to address the traffic density control via ramp metering in a macroscopic level freeway environment. The traffic density control problem is formulated into an output tracking problem and the tracking trajectories are variable with time and iteration change. Rigorous analyses and intensive simulations show that the iterative learning...

Learning can substantially increase the performance of control systems that perform repeating tasks. The aim this letter is to develop an efficient iterative learning algorithm for MIMO with a large number inputs and outputs does not require model knowledge. gradient criterion obtained through dedicated experiments on system. Using judiciously selected randomization technique, unbiased estimate...
